Phone Overheating While in Use
The phone suddenly becomes hot to the touch while in use
Some phone cases are potentially poorly designed and may hinder proper cooling for the device. If your case is bulky and traps heat to your phone, consider replacing it.
If the back of your Samsung Galaxy J3 becomes concerningly hot, a bad battery could be the culprit. In this case, replace your battery with a genuine or certified replacement battery. Do not use cheap or poor quality replacement batteries or chargers.
Forgetting to kill apps running in the background can take a toll on your phone, causing it to overheat. Monitor what apps you are currently using and kill apps that are not in use (Also, long periods of streaming or gaming on your phone can also cause it to overheat. So don’t watch or play games for a long time without giving your device a rest).
Requires Soft Reset
Doing a Soft Reset may resolve an overheating issue. Soft Reset: Turn your device off and remove the cover.->Remove the battery, and wait for 10 seconds before reinserting the battery.->Turn your J3 back on, and see if the problem has been solved.
Requires Hard Reset
Doing a Hard Reset is a drastic method and should be seen as a last-ditch effort. It will erase all of the information stored on the device, including passwords, images, texts and apps. Before you proceed with a hard restart, it is recommended to backup any data beforehand that you may need. Hard Reset: Tap Apps from your Home screen.->Tap the Settings option in this menu.->Find and tap Backup and Reset, and tap Factory Data Reset.->Tap Reset Device, and tap Delete All to confirm your selection.
